摘要

本文提出了一种基于简单电压比较的直流模拟测试技术,该技术是通过仿真找到的最高灵敏度到故障节点。该技术是一种结构性的故障驱动测试方法,可以应用于任何模拟电路,很少额外增加电路。概念验证已在65nm低压晶体管中实现,对灾难性故障和参数故障都显示出良好的故障覆盖率。

Low-cost DC BIST for analog circuits: A case study
This paper presents a DC analog testing technique based on a simple voltage comparison of the highest sensitivity-to-faults node, which is found by simulation. The technique is a structural, fault driven testing approach and can be applied to any analog circuit with very few extra added circuitry. A proof of concept has been implemented in a 65nm low-voltage transconductor, showing good fault coverage for both catastrophic and parametric faults.
